'Thestoker S includes a riser conduit [-6 communicating with the firingopening I2 anddelivering fuel onto a distributing plate H, at the 'rear,of which plate is a jet head l8 from which issuebl-asts of fluid underpressure for-projecting thefuel from the plate 11 into the firebox: Theriser conduit Hi is rigidly supported in any suitable manner, as by abracket l9 which is secured to the backwall -l l. a A frame20 surmountsthe upper end of the riser conduit l6 and-embraces the upper portionofthe firing opening [2. -The frame 20 is provided with a fire door 2|permitting, when open, manual firing of fuel and access to the firebox.Fuel is elevated .through the riser conduit Hi'by ascrewconveyor22 t 1The lower end-oftheriserconduit I 6 is uni versally connectedat 23 to aconduit=24- leading rearwardly toward the tender. 'A" universal andlongitudinally extensible connection 25 joinsthe rearward end of theconduit 24 with theforward end ofthe tender unit of the stoker. Theuniversal connection 23 and the universal and lo'ngi tudinallyextensible connection 25* provi'de'for relative movement 'betweentherigidly mounted riserconduit I6 and rigidly mounted tender unit of thestokerwhen' the locomotive andtender round curves-or pass over switchesand'turntables'. A screw conveyor 26-housed in the conduit 24 isuniversally connected with the screw conveyor 22 by a; link 21andadvances'fuel to the riser conduitlG.

The tender fuel'bin is provided with a floor 28 and the extension 29thereof forward of the bin formsa tender deck. The tender deck 29 andfuel bin floor 28 are provided with a continuous longitudinallyelongated centrally disposed cut out or opening 30. Anopen mouth trough3|, disposed in therwater compartment 15, is arranged to receive fuelfrom the 'bin I4 through the opening 30 in the floor thereof. The uppermarginal sides of the trough 3| are provided with'th'e outwardlyextending flanges 32 and'33; respec tively, overlapping the fuel binfloor 28 adjacent the marginal sides of the opening 39 therein, wherebythe trough 3| is supported by the fuel bin floor. Since the opening 39in the bin floor continues through the tender deck 29, it will be seenthat the trough 3| can be slid rearwardly into place in the watercompartment l5 from the forward end of the tender. After the trough 3|is slid into position, the flanges 32 and 33 are welded to the fuel binfloor 28. as at 34 and 35, providin a water tight seal.

The front wall 36 of the water compartment I5 is cut out at 31 followingthe contour of the trough 3|, permitting insertion of the latter, afterwhich the front wall 36-and the trough 3| are welded as at 38 providinga water tight seal. The trough 3|, which is open at its forward end, isprovided at that end with a short forwardly extending tubular casting39. This tubular casting is provided at its rearward end with anoutwardly extending flange 49 conforming with the shape of the troughand fitting within the forward end of the trough. A weld 4| joining themarginal edge of the flange 49 with the inner surface of the trough 3|rigidly secures the tubular casting 39 with the trough 3|. The forwardend of the tubular casting 39 is connected with the rearward end of theintermediate conduit section 24 by the aforementioned universal andextensible connection 25. A screw conveyor 42 is disposed in the trough3|, the forward end of the screw conveyor extending through the tubularcasting 39 where it is universally connected with the rearward end ofthe screw conveyor 26.

A plurality of transversely extending plates 43 are disposed in thewater compartment |5 and are secured at their lower ends to the floor 44thereof in any suitable manner, as by the angles 45, and similarly, attheir upper ends to the underside of the fuel bin floor 28 by the angles46. The plates 43 are recessed, as at 41, to receive the trough 3|.These plates serve as water battles and also as' additional supports forthe trough by meansof the angles 48 which are securely attached to theplates 43 and fit closely against the sides of the trough.

In the water compartment 5 there is provided a water tight compartment49, disposed rearward of the fuel bin floor ;28 and beneath the rearslope sheet 59 of the fuel bin. The compartment 49 is formed by thefront wall 5|, rear wall 52,' side walls 53 and 54, and the top andbottom walls are formed by the rear slope sheet 59 and the watercompartment floor 44, respectively. The rearward end of the trough 3|extends into the compartment 49 through an opening 55 in the compartmentfront wall 5!. This opening 55 follows the contour of the trough, and.

the weld 56 joining the outside surface of the trough to the wall 5|forms a watertight seal. The various wallsof the compartment 49 arejoined together by suitable means, as by the angles 51, the joints beingmade water tight by suitable means, as by welding. 5

The trough 3|, which as stated before extends into the compartment 49,is open at its rearward end. An end plate 58 forms a closure for theopen rearward end of the trough 3|, and is rigidly secured to the troughby means of an angle 59 extending circumferentially of the trough at 7the rearward end thereof. A casing 69 housing gearing. through which thescrew conveyor 42 is driven, is rigidly secured to the end plate 58 inany suitable manner, as by the bolts 6|, and is provided with aremovable cover 62.

The gear drive mechanism includes a shaft 63 joumaled in the bearings 64and. 65 of the gear casing 69 and gear casing cover 62, respectively.The bearing 64 extends through an opening 66 in the trough end plate 58,allowing the shaft 63 to extend into the trough 3| for drivingattachment in any suitable manner to the screw conveyor 42. A gear 61 iskeyed on the shaft 63 and meshes with a small gear 68 keyed on a shaft69 which is journaled in the bearings 19 and 1| of the gear casing 60and gear casing cover 62, respectively. Keyed on the shaft 69 is a largegear 12 meshing with a small gear 13 keyed on a shaft 14 which isjournaled in the bearings 15 and 16 of the gear casing 69 and gearcasing cover 62, respectively. The shaft 14 is coupled as at 11 to adrive shaft 18 extending longitudinally of the trough 3| to the forwardend of the tender, there being connected to a prime mover or any othersuitable power means not shown.

The. drive shaft 18 is enclosed in a water tight sleeve 19 extendingthrough the water compartment l5 from the compartment 49 through thefront wall 36 of the tank. A weld 89 forms a water tight connectionbetween the sleeve 19 and the front wall 5| of the compartment 49 and aweld 8| forms a water tight connection between the sleeve 19. and thefront wall 36 of the tank. An annular filler piece 82'embraces theportion of the sleeve 19 projecting through the front wall 36 of thetank and fits closely against the front wall 36. The welds 89 and 83provide a water tight connection between the filler piece 82, the sleeve19 and tank front wall 36. A hearing 84 for the; drive shaft 18 isrigidly secured tothe filler piece 82 by the threaded bolts 85 and locknuts 86.

Fuel from the fuelbin |4 enters thetrough 3| through the opening 39 inthe floor thereof. A plurality of plates 81 normally form a closure forthe open mouth of the trough and are arranged to be successively-slidforwardly to uncover successive portions of the opening 39. The plates81 are mounted in guide members 88 and 89 coextensive with the troughand rigidly secured to the upper inner surface of the side walls thereofin any suitable manner'asby the welds 99. Openings-9| are provided inthe plates 81 for insertion of a hook todraw the plates forwardly orpush them rearwardly. A crusher 92 cooperating with the screw conveyor42 for reducing the large lumps of fuel to a size suitable for firing isrigidly secured to the flange 49 of the tubular casting 39 by anysuitable means, as by the bolts 93. T

The rear slope sheet 59 is provided with an opening 94 through whichaccess may be gained to the compartment 49 for purposes of repair orreplacement to the gearing and gear housing 69. A cover 95 normallyforms a closure for the opening 94 and is hinged at 96 to the rear slopesheet 59. The lower edge of the cover 95 overlaps the fuel bin floor 28and is provided with the recesses 91 and 98 affording clearancerespectively, for the trough flange 32 and guide 88, and the troughflange 33 and guide 89.

Forward of the coal gate 99, which is located between the bulkheads I99and HM, there is provided a shoveling platform I92 resting on the tenderdeck 29, the upper surface thereof being level with the upper surface ofthe trough flanges 32 and 33. The shoveling platform I92 forms a coverover the opening 39 in the tender deck 29 and over that portion of thetrough 3| that extends forwardly of the coal gate 99. Theshovelingplatform I02 is'c'ut back or recessed; asshown in Fig. 12 at I03 and 104to fit around the-trough flanges 32 and 33. Rigidly secured' to theundersides of the shoveling platform I02 and in alignment with theguides 88 and 89*ar'e the guides I05 and I06 in which the foremostf theplates 81 can slide beneath the shoveling platform I02. The rearwardendof the shoveling platform" I02 is provided with a centrally disposedrecess I01 arranged to register with the opening 9| in the rearwardportion of the foremost slide plate 81 when it is drawn forwardlybeneath the shoveling platform I02. The recess I01 thus provides foraccess to the slide plate when it is beneath the platform I02, bypermitting insertion of a hook therethrough into the opening 9| of theslide plate.
